Bathroom Exhaust Fans

[hitachi088]

the old one looked like a microwave fan (the one that cools the transformer).

[wangbungal]

do those thing cost a fortune?

[CanFire9]

Any tips for installing a fan in a basement bathroom?

[AsktheBuilder]

@CanFire9 You bet. I have lots of columns about bathroom fans at my AsktheBuilder website. Go there now.

[mmaaxx1198]

That timer switch is really a good idea. And btw, ive installed bathroom fans in the walls! Just keep in mind that warm humid air rises so install it high enough up on the wall to get all the air.

[Averythefanman]

LOL!

[Averythefanman]

The old fan was a NuTone And the new ones are FanTech. Am I correct?

[AsktheBuilder]

@Averythefanman yes. Pick out a prize. :->

Whisper quiiiiieeet

[sadgeneration]

I guess government is only as intelligent as those whom it represents. I'm just upset that when I visit family back in the South, their palatial estate homes are poorly insulated. The weather has cooled off enough for me to not care for the rest of my visit. I may vote when I turn 35. By the way, need an apprentice?

[sadgeneration]

I unfortunately do not have enough time on this earth to do as much research as required; therefore, I am asking the builder. Why does the federal government not mandate builders to use the suggested R-value for insulation in attics and such as studied and put forth by the Department of Energy?

[AsktheBuilder]

@sadgeneration There are so many things that I want to say, but I use my TimCartersFirePit website for most of that. Let's continue with your logic, shall we? Would the next progression be that the Federal Government then regulate the amount of fuel you use? After all, you seem to think they can make better decisions than you. Should they then force you to buy a certain boiler or furnace because it works better? What about using fuel on alternating days as that will keep pipes from freezing?

[SlickManChoux]

It's probably the vibration from the motor transmitted to the fan.

[jamjax]

I have to put a fan through a wall. Cinderblock about 6 -8 inches. I will also need to connect some kinda power supply. Any suggestions on what this should cost or a video on doing it?

[350110thave]

how much cfm do u need ion the fan per size of room? i see use ventilated hoses as well. i have some of these blowes i used for a grow room and i wanna put oin e fo these blowers in my bathroom

[AsktheBuilder]

@350110thave Go to my AsktheBuilder web site. There I have past columns that have a table in it showing you how to size the fan per the square footage of the room.

[jsblgb65]

I don't want a quiet fan, I want a noisy one to add privacy when sitting on the toilet, and I don't care if it's noisy while taking a shower cause the shower itself is noisy.

[herreraalex01]

Tim,

I want to add a vent to the microwave in kitchen, now oddor goes to the inside the house . I find dificult to drill more hole on the roof just to vent the kitchen.

Question : can i add a central exaust system to the house and connect that to the batroom and kitchen and use just one existing vent hole on ther roof?

[Wiredeclipse]

Hello Tim, Could you please tell me what brand the motor/fan is and where can find one? I could not find one at the Home Depot or Lowes. Perhaps I wasn't looking in the right department. Thanks for the informative videos.

[AsktheBuilder]

@Wiredeclipse Sure. It's a FanTech.Their website is fantech net not com. I put three of them in my last house and will absolutely use the same fans in the new house I'm building.

[d1incharge]

not to mention, anything over 25-40$ for a bathroom exhaust fan is too much. Build a house with this mindset you will be underwater in no time.

[AsktheBuilder]

@d1incharge You'll get in trouble quickly with this cheapskate mentality. There's no substitute for quality.

[d1incharge]

Installation of either roof or soffit is a bad idea, particularly in a windy climate. They will produce postive and negative pressures do to the large wing called a roof or wall. If you install the tubing near a roof vent on the underside of the decking, it will be vented out from natural passive ventilation like the rest of the humidity from the house. If you want to lose conditioned air and listen to flap flap flap on windy days, go ahead.

[AsktheBuilder]

@d1incharge I hate to admit it, but you're wrong here. There's nothing wrong installing the vent through a roof. I've never had issues, especially when you use the correct vent cap.

[andtags]

hey i was just wondering about some bathroom fan motors....what is / does that covering around the coils do??

[ryan50ryan]

Man, I could really use a couple of those in my bathroom.

[RussiaversusIsrael]

Hi Tim, great video. I would really like to have 3 exhaust fans/vents, one in my bathroom, kitchen and office area. I'd really prefer if they could just vent off the wall to outside. There are no overhangs at all in any 3 of these areas. I don't care if they are loud. Can you point me in the right direction? Much appreciated!

[REWYRED]

I put one in my bath and one in my kitchen.. Not Fantech ones so they are noisy but they work great

[silver760]

Thing is an inline axial fan like that is hundreds of pounds versus a £30 ceiling fan and a bit of ducting,fine when you have buckets of money to spend.

[hlwpt]

Will both of them vent when one is on? I am buying this house and the roof was just replaced, but the roofers did not run the vents through the roof for the 2 bathrooms and the stove exhaust. i do not want to put 3 more holes in the roof. Can I add in the stove exhaust too? Or should I do it differently? The kitchen is close to the bathrooms.

[AsktheBuilder]

When the fan is on, air is taken from both rooms. Just follow all recommendations by the manufacturer. Get the right fan for a kitchen. Once again, select the one(s) as stated by the mfr. are designed for kitchens.

[8tyman8]

you can go out the sofet or out the side of the house

[AsktheBuilder]

You can, but it would be a huge mistake. The soffit being the worst as the hot humid air seeps up into the attic, especially if there are soffit vents nearby. To a lesser degree this can happen on a wall if there is a roof overhang close to the vent cap. The roof outlet is bulletproof.

[hlwpt]

i have 2 bathrooms which i need to vent. They are next to each other in a 1979 ranch. Is there any concern with connecting the two with one vent fan like this?

Thanks

[AsktheBuilder]

None whatsoever. I'm installing another one just like this in a few days.

[mehrizi78]

What if you have to run electrical too? I have a older house that doesn't have a light in the ceiling its on the wall i would like to see the wiring for that thanks

[toolmaker19]

where do i find one of the inlet boxes for the celing? home depot doesnt carry anything like this and i cannot find one online at all. please help me with this project!

[velvetree]

That's called an inline fan, they have been around for a long time. I agree, its nice to have the noise of the fan. I hate these new hotel bathrooms without fans....(plus if you installed that shape of roof flashing on that angle of a roof anywhere it rains hard, your gonna have electric rain in your bathroom...)

[AsktheBuilder]

I disagree about the flashing. We have torrential driving rains. No leaks.

[NHmadman1]

Thanks for the tips on teh fan and roof vent..Its my next project

[computerepair1970]

Great Video!

Teach a lot!

[RCKenpoandBJJ]

A bathroom fan that makes no noise. I like my privacy with a loud fan thank you very much.

[starstarstar42]

Actually, if you mean that having the noise of the fan will mask your "personal noises" while in the bathroom, that's only partially true. It will only mask the sounds YOU hear, not the sounds people hear through the door or the walls. Its like listening to music through headphones...if you fart really loud, you might not hear it, but the guy 10 feet away definitely did.

[agentxoriginal]

@starstarstar42 Except that's not an accurate comparison. The decibel level of your earphones is not equal to the decibel level of your bodily functions whereas if you have something generating white noise at a similar or equal noise level from the same location then it will help mask or completely hide the other noises.

[sweetyvash]

well tim i really love your video, i mean all of it im from the philippines n i usually do the household work if i think i can manage it, now with your informative show i think i can do most of my house hold problem without paying for some contractor

[sadgeneration]

I like the privacy that noisy exhaust fans offer; I don't want anyone to hear me whispering on the toilet.

[AsktheBuilder]

Perhaps a better comment has never been made on this channel.....

[baseballgrader]

I love your comment LOL

[ttime27514]

this dude looks like he is on coke

[AsktheBuilder]

Nope, but years ago I will admit to drinking way too much cherry pepsi. I'm on the wagon now staying away from as much high-fructose corn syrup as possible.

[froggy7474]

lol...good answer.

[AsktheBuilder]

Uh, try again. Never been employed by them and have no intentions of working for anyone.

[froggy7474]

lol...uh, I was complimenting you on the answer.

Signed....Me, a fantech employee :|

[AsktheBuilder]

Ooooops! My mistake.

[baseballgrader]

I agree

[plotinus1]

Thanks for the video; I wish that tenants had the power to force lazy/cheap landlords to install the modern, energy efficient, quiet fans. I have spent 4 frustrating years living with a super noisy fan and moldy bathroom and it is doubtful that my slumlord would care enough to pay for the installment.

[nickkalisz]

i plan on installing a fan soon and the easiest way is to get power to the new fan through the light would i just cut the black and white wires and splice the to fan? so there would be 3 black wires in the marret 1 from switch,1 to light and 1 to fan and vice versa with white wires?

[AsktheBuilder]

Just make sure the inspector likes this setup

[nickkalisz]

i've been trying to find a wiring diagram for a fan that i may be installing soon.i'm basically getting power off a existing light would i just cut the black and white wires(with power off obviosly) to light from switch and splice the matching wires to the fan? so i would have black wire from switch to marret and the two other black wires from marett going to fan and light and same with white wires?

[AsktheBuilder]

Pay an electrician $10 to draw it out for you.

[Downfacingdog]

Sir! You do go on.

[Blllunttman1]

Do you think I should still be ok with a 100CFM fantech unit? Or should I go higher since I will be running 2 grills? Thanks.

[AsktheBuilder]

Read the specifications. Match the fan to the room's cubic-feet size. Contact the manufacturer and always get from them you are buying the right thing.

[Blllunttman1]

Hey Tim,

I have a 7ft X 7ft bathroom and was looking at the 100 CFM Fantech model.  I currently have a bathroom light/fan combo at the very center of the bathroom. I was wondering if it would be better to replace this with a fantech Grille/light combo and then install a grille above the shower. Then I would connect them to a Y-Pipe from fantech. In your opinion do you think it would have enough coverage with just 1 grille at the center of the bathroom or should I run 2 grilles? Thanks.

[AsktheBuilder]

Run two grills.

[lamedefaultname]

Grr, wish I saw this before I spent part of the weekend installing a traditional style bathfan...

Very cool product! Thanks for the video.

[AsktheBuilder]

Always research *before* you start any project. You may discover that my website can save you time and money. The bright side is that you should not waste any more time again.

[kym1931]

what a cool idea we havent got any thing like that in australia i got to put up with a noisy and a down draught fan lol

[repo1911]

I heard its better to vent to a soffit, because venting vertically to the roof can cause condensation to drip back down into the bathroom?

[AsktheBuilder]

Go out on the web and find photos of what happens when you do what you propose. Some of the water vapor is drawn into the attic space and condenses on the underside of the roof. I discuss in my past columns about Bath Exhaust Fans how to minimize condensation.

[AsktheBuilder]

You need to go to my website and read all of my past columns on Bath Exhaust Fans. There are many.

[Cartiercanshuffle]

@AsktheBuilder we are convinced, we are buying a Fantech Bath Exhaust. On your video there is a slick outlet with a timer. I would like to know where I can find a similar outlet. We will have two switches (one light, one fan) the timer and two outlets. Is this possible. signed novice renovator.

[z47f86y5]

Cool its a Fantech Bath Fan. I work at the facility where we make these.

Great fan and very quiet.

[AsktheBuilder]

Congrats to you! Tell all in the factory we appreciate the product. They really do a good job.

[iam980]

good invention!

[lucidsmog]

Is there a "remote" fan like you have here that doesn't use a roof vent (e.g. if you want to route the air out a soffitt vent in the base of the attic). I've got a finished attic with a bathroom that needs an exhaust and I'm inclined to just run the exhaust like I suggested, but having the remote fan would be excellent. Thanks for the video!

[AsktheBuilder]

You never want to vent to a soffit. The moist air rolls under the soffit and often seeps right back up into the attic. Only vent through the roof. It is EASY. Go watch the companion video that shows how to install the roof vent for this fan.

[rkbaker]

What if you have a slate roof? (or another fragile roofing material). Would you still be dead set against venting through soffit?

[AsktheBuilder]

Yes! A great roofer can put in the needed vent flashing no matter what the roof covering is.

[donflannery]

they also use those types of vacuum fans in the attics to suck radon air out of basements

[allenellisdewitt]

My home is old/odd; actually it's a condo. I wonder if i could modify this to fit the odd design: What i really liked was that it has air back-draft dampers.

[1stdanblkblt]

as far as the pernicious, all they come with is a little bag of screws and the brackets. we end up using only one screw to help hold the J-box on. only half the time we use the brackets. They're really cheesy, end up using angle. again thanks.

[1stdanblkblt]

Well then I stand corrected, because that makes alot of sence. I've never instaled outside CO. so I did not take that into concideration. It's extreamly dry here. Whenever we put in AC a humidifier is manditory on every system. we deal with alot of swamp coolers aswell. So i thank u for putting up with me.

[AsktheBuilder]

You are most welcome. I appreciate your open mind. Not all who comment have that quality.

[1stdanblkblt]

U get above that in a bathroom you suck out either your cold or heat. Did the insulated flex come with the fan too? And what about back-draft dampers? the fan may have one on it but i still put one at EVERY exhaust penetration. the wall cap dose not count. Oh, and u got me on Y. Just never thought of using PVC. Good idea. Look forward to your reply.

[AsktheBuilder]

Yes. As I stated above, all parts you need come with the Fantech fan kits. Look at the video again. The back draft dampers are very good. I have a close up of me activating it with my hand. I thought Panasonic also sells their fans as a kit with all needed parts.

[1stdanblkblt]

I have always used uninsulated doing custom homes in Aspen CO. And let me tell you, those people are picky and yet I haven't had a complaint yet. We also use the Panasonic fans which run virtually silent and they only push 50 to 75 cfm max.

[AsktheBuilder]

You have been able to get away with that because of your extremely dry air out there. When the humidity from a bathroom mixes with normal room air in CO, your dew point is still way below that just about anyplace east of the Mississippi. The condensation issue in exhaust piping is *real* when you are in humid areas.

[1stdanblkblt]

Thank you for replying. And I agree that the insulated flex reduces sound dramatically. But I was just saying that I don't think the insulated flex is necessary for a fart fan.

[AsktheBuilder]

Insulated piping is absolutely necessary if your attic temperature drops below 40F. Please read my past columns about condensation and metal exhaust piping. People without insulation on the pipes think they have roof leaks because so much water drips back through the fan.

[1stdanblkblt]

Not when it's exhaust.

[AsktheBuilder]

Not true. Not by a longshot, and now I see why by your next comment. :-) Geography makes all the difference in the world.

[1stdanblkblt]

why use a plastic Y? Metal is cheaper. If ur worried bout it rustin out use aluminum. still cheaper. No need for insulated flex for fart fans. sound comes from the fan its self. besides there is not enough C.F.M's to make noise though the flex, unless u have some industrial fan. Waste of money bro. So quite fan=quite room. It's all bout the fan man.

[AsktheBuilder]

I respectfully disagree. Please read my past columns on noise and how it travels. All of the parts to install the fan, except for the band clamps, are supplied by the manufacturer. As for pricing, you might want to check your figures. Steel, aluminum and copper prices are at all time highs because of the demand caused by China's growth.

[AsktheBuilder]

Dear gr0leau,

Through the wall. Any number of fans have termination caps made for this. Similar to a dryer vent.

[gr0leau]

I need to put a fan in an existing bathroom on the first floor, So theres no addict space, How would i vent it out, its in the front corner of the house.

[AsktheBuilder]

The fan I used in the video was made by Fantech. They are in Sarasota, FL.

[wbradd3797]

where can I get that type of fan system?
